SMOKING-PIPE.

Specification of Letters Patent.

Patented May 13, 1919.

Application filed June 18, 1918. Serial No. 240,651.

To all whom t may concern.'

Be it known that I, FRANK BEALL, a citizen of the United States, and a resident of the city of New York, borough of Queens, Morris Park, in the county of Queens and State of New York, have invented a new and Improved Smoking-Pipe, of which the following is a full, clear, and eXact description.

This invention relates to smoking pipes, and has particular reference to the provision of means for quick, easy and thorough cleansing of the interior passageway from the bowl to the tip of the mouth piece.

Among the objects, therefore, of the invention is to provide a smoking pipe with facilities carried therein as a permanent part ofthe structurewhereby the bore of the neck and mouth piece may be practically automatically and thoroughly cleansed from all Iaccu-` mulations of nicotine or other offensive matter, by the mere act of separation of the parts.

A further object is to provide a smoking pipe with a longitudinal partition between the -bowl and the tip of the mouth piece providing a saliva well without direct communication to the bowl on one side` of the partition and a freedraft passage between the *bowl and the tip of the mouth piece on the other side of the partition, thus insuring a free draft for the smoke and the preservation of the tobacco in the bowl in a dry state. j

A still further object of the invention is to provide meansof an easy and thorough nature for cleansing the entire stem portion ofy j the pipe without dumping the contents from the bowl. A

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the inven-` tion is not restricted tothe exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had `to the accompanying drawings, in which like reference characters designate `the same parts in the several views, and in which j `Figure 1 is a vertical longitudinal section of tone design of smoking pipe equipped with my improvements.

Fig. 2 is a longitudinal central section of the scraping plug and partition structure detached and on a larger scale than` shown in Fig. 1.

Fig. 3 isa transverse sectional detail on the lineB-Sof Fig. 2; and i Fig. 2l is a view of a different design of pipe `showing my improvements adapted thereto.` j j In carrying out my improvements in a lprac-tical jm-anner I illustrate the same in connection with a smoking pipe comprising a bowl 10, neck l1 integral with the bowl, and a mouth piece or bit 12 detachably connected to the neck, there beine' provided as usual A draft hole is naar thloaom of the bowlcommunicating with a bore through the neck and bit, In the forms of pipes illustrated the neck is counterbored at 14 to receive a cy* lindrical tube 15. This tube is shown as provided with a smooth exterior surface at its outer end acent to the bowl and with an exterior screw thread 16 whereby it is fixed within the end ofthe neck remote from the bowl, and with the threaded end of the tube projected beyond theend of the neck there is provided a nipple for the attachment of the counterbored outer end of the bit. The inner surface of the tube 15 is smooth and cylindrical from end to end. A j j The principal feature of my improvement is shown best in Figs. 2 and 3 and comprises what may be regarded `as a scraping plug 17 embodying a considerable number of different features. This plug may be made of any suitable number of parts, but for convenience I prefer to make the same of one piece of any suitable, sanitary, easy cleans Iable material such as aluminum or its equivalent. j

The outer endof the plug consists of a screw threaded nipple 18 having threaded engagement in the wall of the bowl through which the hole 13 is formed, the eXtreme end of the nipple coming to or nearly to the inner wallv of the bowl. Adjacent to the nipple l8'is the body portion 19 of the plug having a generally cylindrical outer surface fitting closely but slidably in the smooth interior cylindrical surface of the tube 15. The remaining portion of the structure of the plug consists of a spike 20 extending in and along the bore of the mouth piece practically` to the tip thereof. The spike is tapered and of a generally conical form from the body 19 to the tip, the bore of the mouth piece beingof similar form and made to closely it the outer convex surface of the spike.

To provide a suitable smoke draft between to limit myself, however, to any particular form of this passageway vin cross section. The bottom ofthe body 19 beginning at a point not far yremote from the nipple is cut away transversely leaving a saliva well 22,

a wall 23 being observed at the end of the body serving to separate the outer 4end of the wall from the passageway 21 and the bowl. `As shown inFigs. 2 and 3 the bottom of the body is cut away as much as practicable leaving a 1transverse partition 24 with a flat under surface 25, this partition serving to separate the saliva well from the smoke passageway 21. Leading inward toward the tip of .the mouth piece the saliva well 22 has continuous communication with a duct 26 which may be of any suitable form in cross section but indicated as of an inverted trough yshape and constituting a passageway both for the smoke toward the mouth and for the saliva from the' mouth to the well 22. The course of the smoke draft from the'passageway 21 is around or partially around the inner end of the body 19 at the 'counterbore 27 in the outer end of the mouth piece, the tube 15 being somewhat longer than said body of the plug. The meeting edges 28 between the duct 26 and the convex surface of the spike 2O are relai tively sharp, similar to the edges 21.

' With the parts constructed and assembled as thus far described in order to cleanse the pipe stem the smoker has but to unscrew.

the mouth piece 12 from the nipple end of the tube. During the rotation of the stem for unscrewing the same from the tube the scraper plug 16 will either remain stationary or else rotate with the mouth piece and so become detached from the bowl. If the plug remains stationary the relatively sharp edges 28 of the spike will naturally and automatically scrape and cleanse the inner wall of the mouth piece. After the mouth piecev is detached the smoker will then grasp the'spike portion of the plug and unscrew the nipple 18 thereof from the wall of the bowl, which action will cause the sharp edges21of the body to scrape and thoroughly cleanse the inner wall of the tube and exposed surface of the-wall of the bowl between the hole and counterbore into which the tubeis fitted. Any accumulation of filth or deposit thus gathered by the scraping edges of the plug may easily be wiped therefrom by means of a cloth or bit of soft paper. The cleansing operation is now complete ready for reassemblage. The contents of the bowl even though alive need not be disturbed in this cleansing operation. Ordinarily the tube 15 need not be removed for this purpose, but it may be removed at any time obviously by unscrewing the same from the neck.

Fig. 41- indicates the adaptation of my improvement to a pipe having a curved mouth piece 12. The spike portion 20 of the scraping plug obviously may be similarly curved, in order to introduce it into the mouth piece. In this form of the invention the scraping plug and mouth piece after being assembled obviously must rotate t0- gether and so are connected to and disconnected from the nipple end of the tube 15 simultaneously, otherwise the parts are or may be the same as above described and hence are similarly indicated by reference characters.

I claim:

1. In a smoking pipe, the combination of a bowl, a neck fixed thereto, a mouth piece carried by the neck, a portion of the structure between the bowl and the mouth piece being oounterbored forming a saliva pit, a scraping plug comprising a body fitted in the saliva pit, said plug engaging the side walls of the pit but being provided with reduced portions at the top and bottom and being shorter than the saliva pit providing a smoke passage from the upper reduced portion around the end of the body vadjacent to the mouth piece, and a spike integral with the body and extending through the mouth piece and having a groove along its lower side forming a continuation of the smoke passage aforesaid, said body being provided with sharp edges lto scrape the surface of the pit when relative rotation is set up between the plug and the neck.

2. In a smoking pipe, the combination with a bowl, a neck fixed thereto, and a mouth piece secured to the neck, said neck and mouth piece being counter-bored forming a saliva pit, of a scraping plug compris ing a body fitted in the saliva pit, the side walls of the body bearing against the side walls of the pit, but being shorter than the pit, providing for a smoke passage around one end of the body, said plug also including a nipple threaded into the wall of the bowl between the bowl and the neck, and a spike leading from the body to the tip of the mouth piece, said body and spike being provided with sharp edges to scrape the surfaces of the pit and mouth piece bore 4when relative rotation is set up between the plug and the other parts.
